Analysis of Group B Streptococcal Isolates from Infants and Pregnant Women in Portugal Revealing Two Lineages with Enhanced Invasiveness

16 Aug 2007

Abstract excerpt

The populations of group B streptococcus (GBS) associated with vaginal carriage in pregnant women and invasive neonatal infections in Portugal were compared. GBS isolates were characterized by serotyping, pulsed-field gel electrophoresis (PFGE) profiling, and multilocus sequence typing (MLST). Serotypes III and V accounted for 44% of all colonization isolates (n = 269), whereas serotypes III and Ia amounted to...
